Lets talk about Yang Zi as Yan Dan/ Bai PiaoLiang (you will laugh when you heard this name)
Yang Zi has portrayed this character really good, maybe this character is similar to Jin Mi (Ashes of Love) Jin Mi and Yan Dan almost has the same personality, carefree, helpful and generous to everyone. I will make a comparison between these two.

Yan Dan is really smart, especially with Weiqi game (Chinese Chess) even Ying Yuan (our male lead, Cheng Yi) praised her that she's one of a kind. Even though she doesn't care much about Cultivation like her twin sister (Zhi Xi) but she is a fast learner, she values love and friendship. Unlike Jin Mi, since birth she doesn't what is Love because she had the 'Unfeeling Pill' thats why she doesnt know what is Love.

For Cheng Yi as Emperor Ying Yuan /Tang Zhou/ Xuan Ye. This is my first drama watching his portrayed. I would say his emotions, his character, everything fits this actor so well. I have no ideas how many times I cried watching this Chinese drama. I watched Good Bye My Princess, I was sad for days. But for this one, throughout the drama since the beginning to the end, i cried a RIVER!!! maybe after this drama, i have to watch Love and Redemption, Cheng Yi as Yu Sifeng. I have to be prepare again T_T

Guys, if you hesitate to watch. I would say please give it a try for the first 10 episodes. Because you will love their chemistry and plus you guys HAVE TO GO THROUGH WHAT I WENT THROUGH!!! ALL THOSE EMOTIONS, SLEEPLESS NIGHTS, THE LAUGHS EVERYTHING. yeah im joking but i love love this drama so much. I come back and forth watching my favourite scenes.
